Post by jgaadesh » Oct 27, 2017 9:53 pm

Hello Team,

We are facing issue taking backup on external hard drive of HYPER-V hosted VM's.

I have tried scanning the managed server & got errors Disks & volumes discovery failed error: Disk extents are not specified... Host discovery failed.

Checked the drives its working fine. could you please advise on this..

Hi Aadesh, please continue working with your support engineer on that, a closer look at your setup and most likely log files is required here. Thanks.

Hello!

I have such problem. When I try to make backup or Host discovery, I get an error: Disks and volumes discovery failed Error: Disk extents are not specified for the volume 'D:\'.
I use VeraCrypt to crypt my VM's. I make the crypt container on disk E and set a letter D to this container. May be it's a problem in working Veeam B&R?

Hi bkpusr,

You installed Veeam Backup & Replication (on a physical or virtual server, doesn't really matter at this moment). Then you add your hyper-v host to the managed servers. Is that the first step you took?

Hi Mike,

Thank for response. I found, that this problem with VeraCrypt, because partitions, created by it, does not work with VSS service.

Ah,
Yes, I think I understand it now better. VeraCrypt (and others for that matter) have indeed issues with VSS. Not sure if it is still the problem but try running chkdsk on a veracrypt partition... It won't work.

Thanks!

I changed encryption partition to BitLocker and now Veeam R&B works fine.
